: The part of study samples was included in the previous multicenter study in which our institution participated (128 HCCs [35.9%], <i>Lee et al Liver Cancer 2021;10:25–37 Laparoscopic Liver Resection versus Percutaneous Radiofrequency Ablation for Small Single Nodular Hepatocellular Carcinoma: Comparison of Treatment Outcomes</i>). The focus of LI-RADS category on gadoxetic acid-enhanced MRI in our study was quite different from the previous study by Lee et al focused on the tumor location. In addition, we included more patients and a longer follow-up time.A total of 57 HCCs from reference (Cha et al Eur Radiol 2021 Sep;31(9):6555-6567 <i>Rim-arterial enhancing primary hepatic tumors with other targetoid appearance show early recurrence after radiofrequency ablation</i>] were previously reported. The previous study only evaluated the treatment outcome of RFA. In addition, there are different inclusion criteria and imaging analysis methods.
